USB: option: add support for Huawei E353 device

BugLink: http://bugs.launchpad.net/bugs/793702

commit 610ba42f29c3dfa46a05ff8c2cadc29f544ff76d upstream.

I am sharing patch to the devices/usb/serial/option.c. This allows
operation of Huawei E353 broadband modem using the “option” driver. The
patch simply adds new constant with proper product ID and an entry to
usb_device_id. I worked on the 2.6.38.6 sources. Tested on Dell inspiron
1764 (i3 core cpu) and brand new Huawei E353 modem, Fedora 15 beta.

Looking at the type of change, i doubt it has potential to introduce
problems in other parts of kernel or the driver itself.
